Sometimes being a jack of all trades instead of a specialist is a good thing.

I never saw anyone here saying they were a specialist.

I grew up on revolvers, carried one as a duty gun for 13 years and was drug kicking and screaming into the semi auto world. Fast forward almost 20 years and I know that the best handgun for SD against 2 legged critters is a semi auto. I still hunt with revolvers and carry one as a bug.

This is where cold hard facts should be the determining factor.

I agree OG that one should be able to manipulate many types of guns, that comes with establishing basic familiarity the moment you pick it up ( where is that safety?). I guess I was fortunate growing up around a gun shop and tinkering with guns from an early age.
